The trouble is, I can not find [2] on MathSciNet or Google. I also looked at his Selected works without luck. Of course, there are many papers that are forthcoming but never materialized, but this one even has the journal name attached to it! So

What happened to Auslander paper [2] above?

Note that [1] is an influential paper (still being quoted very recently). I enjoyed it a lot, and would really like to read [2].

UPDATE: both Professor Buchsbaum and Professor Reiten have graciously replied to my query about this missing paper. Unfortunately, neither of them know what happened.
